The epidemiology of schistosomiasis and hookworm was studied in seasonal transmission settings in the northern part of C\u00f4te d\u2019Ivoire.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methodology<\/jats:title>\n<jats:p>In August 2018, a cross-sectional study was conducted. Urine and stool samples were collected from 742 individuals aged 6\u201396 years in 16 localities from four departments in northern C\u00f4te d\u2019Ivoire. Urine samples were examined by a filtration method for quantification of <jats:italic>Schistosoma haematobium<\/jats:italic> eggs. Stool samples were subjected to duplicate Kato-Katz thick smears and eggs of <jats:italic>Schistosoma mansoni<\/jats:italic> and soil-transmitted helminths (STHs) were counted. Additionally, a questionnaire was administered to determine demographic characteristics and to identify risk factors of schistosomiasis and STHs. Malacologic surveys were carried out at water points that are contacted by humans and animals.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Principal findings<\/jats:title>\n<jats:p>The prevalence of schistosomiasis was very low. Only two cases of <jats:italic>S<\/jats:italic>. <jats:italic>mansoni<\/jats:italic> were found (0.3%, 95% confidence interval [CI]: 0.1\u20131.0%). The distribution of <jats:italic>S<\/jats:italic>. <jats:italic>haematobium<\/jats:italic> was focal, with cases found only in two departments; Ferkess\u00e9dougou (5.4%, 95% CI: 2.5\u20139.9%) and Ouangolodougou (2.7%, 95% CI: 0.9\u20136.3%). Hookworm was the only STH species observed with a prevalence of 1.5% (95% CI: 0.8\u20132.8%). A higher risk of <jats:italic>S<\/jats:italic>. <jats:italic>haematobium<\/jats:italic> infection was observed in males compared to females, but the difference was not statistically significant (2.3% versus 1.3%, odds ratio [OR]: 1.5, 95% CI: 0.8\u20132.7). Participants aged 16\u201320 years showed the highest prevalence of <jats:italic>S<\/jats:italic>. <jats:italic>haematobium<\/jats:italic>. A total of 111 human- and animal-water contact points were identified at 47 water sources. Three potential intermediate host snails of schistosomes were collected; namely, <jats:italic>Bulinus forskalii<\/jats:italic> (n = 761), <jats:italic>Bulinus truncatus<\/jats:italic> (n = 205), and <jats:italic>Biomphalaria pfeifferi<\/jats:italic> (n = 1). Yet, only one specimen of <jats:italic>Bu<\/jats:italic>. <jats:italic>truncatus<\/jats:italic> was found to be shedding schistosome cercariae.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions\/Significance<\/jats:title>\n<jats:p>This study confirms very low transmission of schistosomiasis and hookworm in northern C\u00f4te d\u2019Ivoire.
